Headset mic picking up output audio

[josh107]

Greetings,

 

I recently my hands on HyperX Cloud Stinger headset.

It has single 3.5mm output + splitter for speaker and microphone.

 

Its picking up audio that I'm hearing ( music, game sounds etc... ).

 

The issue persists even if mic is muted.

 

If I plug in some random desktop mic I have laying around, the issue goes away.

 

What could I try to find out if its either hardware ( motherboard or headset itself ) or software issue?

The issue is probably caused of having bad onboard audio. 

 

Issue seems to go away when using echo cancellation.
